# What is the Residential Proxy package?

YumiProxy's Residential Proxy products are divided into Basic Edition and Advanced Edition. The products are sold by GB, with no time limit – as long as the purchased traffic is not fully used, it remains valid permanently. The difference is that the Advanced Edition has a CDKey distribution function, allowing you to generate CDKeys to share with other users.
